[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , the auger 6 is in contact with the inner wall of the feed hopper 1 and the inner wall of the drying kiln feed inlet 7. The auger 6 can convey the raw materials by rotation. One end of the first spring 8 is fixedly connected with the square rod shaft 5, and the other end of the first spring 8 is fixedly connected with the square-hole pipe 3. The first spring 8 can support the square rod shaft 5 by elastic force. The middle part of the inner wall of the feed hopper 1 is fixedly connected with a support frame 9. The support frame 9 and the square-hole pipe 3 are connected by a bearing. The second bevel gear 12 is meshed with the first bevel gear 10. The inclined plane frame 15 is slidably connected with the inclined plane ring 14. The support frame 9 can make the rotation of the square-hole pipe 3 more stable.

[0022] Please refer to Figure 1 , Figure 2 ,Figure 4 , the hammering mechanism 4 includes a support frame 41.

One end of the support nail 42 away from the support frame 41 is fixedly connected with a hammer head 43. A second spring 44 is arranged outside the support nail 42. The upper part of the inner wall of the feed hopper 1 is fixedly connected with a plurality of arc blocks 45 distributed in a ring shape.

[0023] The specific implementation process of the present utility model is as follows: When in use, the raw materials are placed inside the feed hopper 1, and then the motor 11 is started.

When the hammer head 43 contacts the arc block 45 during the rotation, the hammer head 43 strikes the outside of the arc block 45, which can drive the feed hopper 1 to vibrate and compress the second spring 44. When the hammer head 43 disengages from the arc block 45, the second spring 44 resets. The second spring 44 can drive the hammer head 43 to strike the inner wall of the feed hopper 1 by its elastic force, and then the feed hopper 1 can be hammered again, so that the raw materials inside the feed hopper 1 can be vibrated through vibration to avoid the accumulation of raw materials.
